Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER” ECS00IY4
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used alongwith a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certaintypes of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRSsystem uses the seat belt switches to determine the front air bag deployment, and may only deploy one frontair bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.Information necessary to service the system safely is included in the SRS and SB section of this Service Man-ual.WARNING: To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and AirBag Module, see the SRS section.
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in thisService Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses orharness connectors.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectECS00IY5
NOTE: This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS). Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position. Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lockmechanism is adopted on the key cylinder.For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock andsteering wheel rotation will become impossible.If steering wheel rotation is required when battery power is interrupted, follow the procedure below beforestarting the repair operation.
OPERATION PROCEDURE1. Connect both battery cables.
NOTE:Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, thesteering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can berotated.
4. Perform the necessary repair operation.5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)6. Perform a self-diagnosis check of all control units using CONSULT-II.

Precautions for On Board Diagnostic (OBD) System of CVT and Engine ECS00IY6
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn thedriver of a malfunction causing emission deterioration.CAUTION: Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative termi-
nal before any repair or inspection work. The open/short circuit of related switches, sensors, sole-noid valves, etc. will cause the MIL to light up.
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector willcause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,dirt, bent terminals, etc.)
Be sure to route and secure the harnesses properly after work. Interference of the harness with abracket, etc. may cause the MIL to light up due to a short circuit.
Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tubemay cause the MIL to light up due to a malfunction of the EVAP system or fuel injection system,etc.
Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM andECM before returning the vehicle to the customer.

CAN Communication ECS00IQL
SYSTEM DESCRIPTION CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-tiplex communication line with high data communication speed and excellent error detection ability. Many elec-tronic control units are equipped onto a vehicle, and each control unit shares information and links with othercontrol units during operation (not independent). In CAN communication, control units are connected with 2communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.Each control unit transmits/receives data but selectively reads required data only. For details, refer to ! Hyper-link Error ! .

Line Pressure and Secondary Pressure Control ECS00IQN
When an input torque signal equivalent to the engine drive force is sent from the ECM to the TCM, theTCM controls the line pressure solenoid valve and secondary pressure solenoid valve.
This line pressure solenoid controls the pressure regulator valve as the signal pressure and adjusts thepressure of the operating oil discharged from the oil pump to the line pressure most appropriate to thedriving state. Secondary pressure is controlled by decreasing line pressure.
NORMAL CONTROLOptimize the line pressure and secondary pressure, depending on driving conditions, on the basis of the throt-tle position, the engine speed, the primary pulley (input) revolution speed, the secondary pulley (output) revo-lution speed, the brake signal, the PNP switch signal, the lock-up signal, the voltage, the target gear ratio, thefluid temperature, and the fluid pressure.
FEEDBACK CONTROLWhen controlling the normal fluid pressure or the selected fluid pressure, the secondary pressure can be setmore accurately by using the fluid pressure sensor to detect the secondary pressure and controlling the feed-back.
Shift Control ECS00IQO
In order to select the gear ratio which can obtain the driving force in accordance with driver's intention and thevehicle condition, TCM monitors the driving conditions, such as the vehicle speed and the throttle position andselects the optimum gear ratio, and determines the gear change steps to the gear ratio. Then send the com-mand to the step motor, and control the flow-in/flow-out of line pressure from the primary pulley to determinethe position of the moving-pulley and control the gear ratio.

OVERDRIVE-OFF MODEUse this position for the improved engine braking.
“L” POSITIONBy limiting the gear range to the lowest position, the strong drivingforce and the engine brake can be secured.
DOWNHILL ENGINE BRAKE CONTROL (AUTO ENGINE BRAKE CONTROL)When downhill is detected with the accelerator pedal released, the engine brake will be strengthened up bydownshifting so as not to accelerate the vehicle more than necessary.
ACCELERATION CONTROLAccording to vehicle speed and a change of accelerator pedal angle, driver's request for acceleration and driv-ing scene are judged. This function assists improvement in acceleration feeling by making the engine speedproportionate to the vehicle speed. And a shift map which can gain a larger driving force is available for com-patibility of mileage with driveability.

ON BOARD DIAGNOSTIC (OBD) SYSTEM PFP:00028
Introduction ECS00IQR
The CVT system has two self-diagnostic systems.The first is the emission-related on board diagnostic system (OBD-II) performed by the TCM in combinationwith the ECM. The malfunction is indicated by the MIL (malfunction indicator lamp) and is stored as a DTC inthe ECM memory, and the TCM memory.The second is the TCM original self-diagnosis performed by the TCM. The malfunction is stored in the TCMmemory. The detected items are overlapped with OBD-II self-diagnostic items. For detail, refer to ! Hyper-linkError ! .
OBD-II Function for CVT System ECS00IQS
The ECM provides emission-related on board diagnostic (OBD-II) functions for the CVT system. One functionis to receive a signal from the TCM used with OBD-related parts of the CVT system. The signal is sent to theECM when a malfunction occurs in the corresponding OBD-related part. The other function is to indicate adiagnostic result by means of the MIL (malfunction indicator lamp) on the instrument panel. Sensors, switchesand solenoid valves are used as sensing elements.The MIL automatically illuminates in One or Two Trip Detection Logic when a malfunction is sensed in relationto CVT system parts.
One or Two Trip Detection Logic of OBD-II ECS00IQT
ONE TRIP DETECTION LOGICIf a malfunction is sensed during the first test drive, the MIL will illuminate and the malfunction will be stored inthe ECM memory as a DTC. The TCM is not provided with such a memory function.
TWO TRIP DETECTION LOGICWhen a malfunction is sensed during the first test drive, it is stored in the ECM memory as a 1st trip DTC(diagnostic trouble code) or 1st trip freeze frame data. At this point, the MIL will not illuminate. — 1st tripIf the same malfunction as that experienced during the first test drive is sensed during the second test drive,the MIL will illuminate. — 2nd tripThe “trip” in the “One or Two Trip Detection Logic” means a driving mode in which self-diagnosis is performedduring vehicle operation.
OBD-II Diagnostic Trouble Code (DTC) ECS00IQU
HOW TO READ DTC AND 1ST TRIP DTCDTC and 1st trip DTC can be read by the following methods.( with CONSULT-II or GST) CONSULT-II or GST (Generic Scan Tool) Examples: P0705, P0720 etc.These DTC are prescribed by SAE J2012.(CONSULT-II also displays the malfunctioning component or system.) 1st trip DTC No. is the same as DTC No. Output of the diagnostic trouble code indicates that the indicated circuit has a malfunction. How-
ever, in case of the Mode II and GST, they do not indicate whether the malfunction is still occurringor occurred in the past and returned to normal.CONSULT-II can identify them as shown below, therefore, CONSULT-II (if available) is recom-mended.
A sample of CONSULT-II display for DTC and 1st trip DTC is shownon the next page. DTC or 1st trip DTC of a malfunction is displayedin SELF-DIAGNOSTIC RESULTS mode for “ENGINE” with CON-SULT-II. Time data indicates how many times the vehicle was drivenafter the last detection of a DTC.
BCIA0030E
CVT-28
ON BOARD DIAGNOSTIC (OBD) SYSTEM
If the DTC is being detected currently, the time data will be “0”.
If a 1st trip DTC is stored in the ECM, the time data will be “1t”.
Freeze Frame Data and 1st Trip Freeze Frame DataThe ECM has a memory function, which stores the driving condition such as fuel system status, calculatedload value, engine coolant temperature, short term fuel trim, long term fuel trim, engine speed and vehiclespeed at the moment the ECM detects a malfunction.Data which are stored in the ECM memory, along with the 1st trip DTC, are called 1st trip freeze frame data,and the data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-IIor GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. Fordetails, refer to ! Hyper-link Error ! .Only one set of freeze frame data (either 1st trip freeze frame data or freeze frame data) can be stored in theECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priorityfor 1st trip freeze frame data, and it is updated each time a different 1st trip DTC is detected. However, oncefreeze frame data (2nd trip detection/MIL on) is stored in the ECM memory, 1st trip freeze frame data is nolonger stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the fol-lowing priorities to update the data.
Both 1st trip freeze frame data and freeze frame data (along with the DTC) are cleared when the ECM mem-ory is erased.
HOW TO ERASE DTCThe diagnostic trouble code can be erased by CONSULT-II, GST or ECM DIAGNOSTIC TEST MODE asdescribed following. If the battery cable is disconnected, the diagnostic trouble code will be lost within 24 hours. When you erase the DTC, using CONSULT-II or GST is easier and quicker than switching the mode
selector on the ECM.The following emission-related diagnostic information is cleared from the ECM memory when erasing DTCrelated to OBD-II. For details, refer to ! Hyper-link Error ! . Diagnostic trouble codes (DTC) 1st trip diagnostic trouble codes (1st trip DTC) Freeze frame data

DTC Inspection Priority Chart ECS00IQW
If some DTCs are displayed at the same time, perform inspections one by one based on the following prioritychart.NOTE:If DTC “U1000 CAN COMM CIRCUIT” is displayed with other DTCs, first perform the trouble diagnosisfor “DTC U1000 CAN COMMUNICATION LINE”. Refer to ! Hyper-link Error ! .
Fail-safe ECS00IQX
The TCM has an electrical fail-safe mode. This mode makes it possible to operate even if there is an error in amain electronic control input/output signal circuit.
FAIL-SAFE FUNCTION If any malfunction occurs in a sensor or solenoid, this function controls the CVT to make driving possible.
Output Speed Sensor (Secondary Speed Sensor)The shift pattern is changed in accordance with throttle position when an unexpected signal is sent from theoutput speed sensor (secondary speed sensor) to the TCM. The overdrive-off mode is inhibited, and the tran-saxle is put in “D”.
Input Speed Sensor (Primary Speed Sensor)The shift pattern is changed in accordance with throttle position and secondary speed (vehicle speed) whenan unexpected signal is sent from the input speed sensor (primary speed sensor) to the TCM. The sport modeis inhibited, and the transaxle is put in “D”.
PNP SwitchIf an unexpected signal is sent from the PNP switch to the TCM, the transaxle is put in “D”.
CVT Fluid Temperature SensorIf an unexpected signal is sent from the CVT fluid temperature sensor to the TCM, the gear ratio in use beforereceiving the unexpected signal is maintained or the gear ratio is controlled to keep engine speed under 3500rpm.
Transmission Fluid Pressure Sensor A (Secondary Pressure Sensor) If an unexpected signal is sent from the transmission fluid pressure sensor A (secondary pressure sensor)
to the TCM, the secondary pressure feedback control is stopped and the offset value obtained before thenon-standard condition occurs is used to control line pressure.
If transmission fluid pressure sensor A (secondary pressure sensor) error signal is input to TCM, second-ary pressure feedback control stops, but line pressure is controlled normally.
Pressure Control Solenoid A (Line Pressure Solenoid)If an unexpected signal is sent from the solenoid to the TCM, the pressure control solenoid A (line pressuresolenoid) is turned OFF to achieve the maximum fluid pressure.
Pressure Control Solenoid B (Secondary Pressure Solenoid)If an unexpected signal is sent from the solenoid to the TCM, the pressure control solenoid B (secondary pres-sure solenoid) is turned OFF to achieve the maximum fluid pressure.
Torque Converter Clutch SolenoidIf an unexpected signal is sent from the solenoid to the TCM, the torque converter clutch solenoid is turnedOFF to cancel the lock-up.
Step MotorIf an unexpected signal is sent from the step motor to the TCM, the step motor coil phases “A” through “D” areall turned OFF to hold the gear ratio used right before the non-standard condition occurred.

TROUBLE DIAGNOSIS
CVT Lock-up Select SolenoidIf an unexpected signal is sent from the solenoid to the TCM, the CVT lock-up select solenoid is turned OFF tocancel the lock-up.
TCM Power Supply (Memory Back-up)Transaxle assembly is protected by limiting the engine torque when the memory back-up power supply (forcontrolling) from the battery is not supplied to TCM. Normal statues is restored when turning the ignition switchOFF to ON after the normal power supply.
How to Perform Trouble Diagnosis for Quick and Accurate Repair ECS00IQY
INTRODUCTIONThe TCM receives a signal from the vehicle speed sensor, PNP switch and provides shift control or lock-upcontrol via CVT solenoid valves.The TCM also communicates with the ECM by means of a signalsent from sensing elements used with the OBD-related parts of theCVT system for malfunction-diagnostic purposes. The TCM is capa-ble of diagnosing malfunctioning parts while the ECM can store mal-functions in its memory.Input and output signals must always be correct and stable in theoperation of the CVT system. The CVT system must be in goodoperating condition and be free of valve seizure, solenoid valve mal-function, etc.
It is much more difficult to diagnose an error that occurs intermit-tently rather than continuously. Most intermittent errors are causedby poor electric connections or improper wiring. In this case, carefulchecking of suspected circuits may help prevent the replacement ofgood parts.A visual check only may not find the cause of the errors. A road testwith CONSULT-II (or GST) or a circuit tester connected should beperformed. Follow the ! Hyper-link Error ! .
Before undertaking actual checks, take a few minutes to talk with acustomer who approaches with a driveability complaint. The cus-tomer can supply good information about such errors, especiallyintermittent ones. Find out what symptoms are present and underwhat conditions they occur. A “DIAGNOSTIC WORKSHEET” asshown on the example (Refer to ! Hyper-link Error ! ) should be used.Start your diagnosis by looking for “conventional” errors first. This willhelp troubleshoot driveability errors on an electronically controlledengine vehicle.Also check related Service bulletins.

DTC U1000 CAN COMMUNICATION LINE PFP:23710
Description ECS00IRA
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-tiplex communication line with high data communication speed and excellent malfunction detection ability.Many electronic control units are equipped onto a vehicle, and each control unit shares information and linkswith other control units during operation (not independent). In CAN communication, control units are con-nected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmissionwith less wiring. Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis Logic ECS00IRB
This is an OBD-II self-diagnostic item. Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-II is detected when TCM cannot
communicate to other control units.
Possible Cause ECS00IRC
Harness or connectors(CAN communication line is open or shorted.)
DTC Confirmation Procedure ECS00IRD
NOTE:If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF andwait at least 10 seconds before performing the next test.After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-firm the malfunction is eliminated.
WITH CONSULT-II1. Turn ignition switch ON. (Do not start engine.)2. Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.3. Start engine and wait for at least 6 seconds.4. If DTC is detected, go to ! Hyper-link Error ! .
